GSC Evo 9 Billet Camshafts

GSC Power-Division’s Billet Evo 9 S1 cams are designed for those with a stock turbo all the way to a GT30/50Trim. These cams will not sacrifice any bottom end loss over stock cams; nothing but gains and will promote faster spooling of the upgraded turbos. Gains of 25-40whp (depending on Turbo) have been seen by simply bolting the S1 cams in. Designed for a rev range of 3000-8000rpms, these cams work well on the stock valve springs. 300-450whp camshaft.

GSC P-D Evo 9 Stage 2 Cams

The Full Billet S2 cams are designed for those with more power in mind or a larger turbo. No low end power is lost vs the stock cams when used with the larger turbos. The S2 cams will show gains of 50-70whp over the stock cams and in some cases more in the higher RPMS. Great for 2.0L engines revving to 9000rpms or for Stroker motors revving to 8000rpms. The S2 Cams are suggest to run on our upgraded Beehive valve spring replacement or can be run at the stock revlimit and factory boost on the stock spring. Designed for a rev range of 4000-9000 RPMS(2.0L or 3000-8000 2.2L+), 400-700whp applications. S2 cams can run on Factory ECU with custom flashing.
**If using aftermarket cam gears(especially AEM) check the bolt lenght, some cam gears are too thick for the OEM bolt on the Billet cams, a 40mm underhead lenght bolt may be necessary in this case**

GSC P-D Stroker R2 Cams

We worked with English Racing on this profile to offer the 2.2-2.4 lower reving engines with mivec control a profile that would allow for more air volume in the cylinder to help fill the larger displacement engines and make more midrange and top end power. The billet 7009R2 is a high lift very aggressive profile with a short overall duration to keep a lower usable rpm band. The 7009R2 is designed to rev between 4000-8500 rpms and should be used with a stroked engine or added displacement engine. The peak lift of 12.1mm intake and 11.9mm exhaust will require upgraded valve springs and a titanium retainer with special attention to seal to retainer clearance. With the lift of this profile it is suggested to only use the 5041/5040 Ti retainer and spring kits do to valve seal to retainer clearance. The 5041 can be used to 40+psi and the 5040 to 32psi on the R2 profile at 8500rpms without float or flutter issues. The profile will work fine on the OEM Rocker Arm and the Zero-tick lifter or with the OEM lifter. We have seen gains of 25-30whp over the S2 profile on the stroked applications with much more possible when used with a ported head and aftermarket intake manifold.
